The main objective of this tutorial is to present the basic concepts on the instantaneous p-q Theory and them show its applicability for controlling switching converters connected in a micro-grid. These converters can be used for connecting renewable energy sources (solar, wind, and others) to the microgrids or for harmonic, reactive power or unbalance compensation, and even for voltage regulat...

In economics and regional science we observe recently a growing interest in the use of non-linear dynamic models. In particular nonlinear deterministic models appear quite appealing, since they may exhibit both oscillating and chaotic behaviour and hence may provide an endogenous explanation of the periodicity and/or irregularity observed in the dynamics of spatial economie systems. In this pap...

MOTIVATION Oscillating signals produced by biological systems have shapes, described by their Fourier spectra, that can potentially reveal the mechanisms that generate them. Extracting this information from measured signals is interesting for the validation of theoretical models, discovery and classification of interaction types, and for optimal experiment design. RESULTS An automated workflo...

[Purpose] The aim of this study was to evaluate the effect of oscillating electrical field stimulation on motor function recovery and myelin regeneration in rats with spinal cord injury. [Subjects and Methods] A rat model of spinal cord injury was constructed by using the Allen weight-drop method. These rats were randomly divided into normal, spinal cord injury, and spinal cord injury + oscilla...
